Meningitis outcomes | |||

Hospital admission for meningitis or clinic assessment for seizures | 7.0 | 22%‡ | 1.6 |
Hospital admission for meningitis | 5.4 | 16% | 0.87 |
Probable bacterial or confirmed Hib | 0.86 | 55%‡ | 0.47 |
Microbiologically confirmed Hib | 0.19 | 86%‡ | 0.16 |
Hib=Haemophilus influenzae type b. VE=Vaccine effectiveness. VPDI=vaccine-preventable disease incidence.
All incidences are per 1000 person-years of follow-up.
VPDI is calculated as the vaccine effectiveness multiplied by the control group incidence, and is shown per 1000 person-years of follow-up in children from age of first vaccination to age 2 years.
VE has 95% CIs that exclude 0.
